Advanced inspection/testing equipment uses a laser scanner to scan the heating end of the electric heater, ensuring that the distance between the thermocouple working end of the electric heater and the heating end of the heating element, as well as the distance between the heating end of the heating element and the bottom, meet the standard requirements. Use a thermocouple automated calibration system to calibrate temperature controlled thermocouples to ensure their accuracy and electrical performance meet standard requirements. Analyze stainless steel materials with a spectrometer to ensure the use of the best materials to produce the highest quality electric heaters. 2.
